Camille Wormser 01d0293bc5 Code is now almost up to the specification: Primitive::Id everywhere, 
the KD-tree uses decorated points to return the Id too. 

There are just a few boost::optional to add in the traits, where we still
use the old bool intersection(..., Result&) approach, and some modernization 
to do in the distance computation things.

Everything compiles.

I have removed the funtion closest_primitive from the code and documentation, 
since it would not be consistent with the rest of the interface, and would not
be faster than closest_point_and_primitive.

I think we are almost done, not only for the documentation, but for the code too.

Camille Wormser 811f08256b added missing types to the AABBTraits concept. 
(I have added the missing methods for the distance queries too)

Camille Wormser 1f4c9a150e cleaning of the traits. Not finished yet. 
I've removed all references to the Sphere (it was used only internally anyway), 
because we will not use it anymore: we replace its use by direct calls to is_closer.

Camille Wormser fa539afc07 in the description of do_intersect and intersection, in the GeomTraits, 
primitive --> geometric object
(some are queries, some are primitives)
 2009-05-08 10:37:07 +00:00
Camille Wormser 4f329a0761 the GeomTraits does not provide the query types at all. 2009-05-08 10:34:03 +00:00
Camille Wormser 61aee20d79 typos + clearer explanation of the role of the ids 
(used to refer to the primitives in the outputs, but need not be unique)

Camille Wormser 38da93cbca text improvement and typos for distances 2009-05-08 09:55:28 +00:00
Camille Wormser a03de6bb32 we do not need intersection for any_intersected_primitive 2009-05-08 09:46:34 +00:00
Camille Wormser 794157450f allocation detail in the constructor 2009-05-08 09:45:46 +00:00
Camille Wormser 8358202dde The requirement on the constructor was a bit too strong: we do not need 
the fact that the iterator range is a container of objects of type Datum.

Quite the contrary: it can be halfedges_begin/end. Hence, we should keep 
only the requirement that Primitive is constructible from it (that's 
really what we use in practice).

Camille Wormser 31e85b74de still polishing (just typos) 2009-05-08 09:27:27 +00:00
Camille Wormser 986f01d0d5 doing some polishing on the documentation... (not finished yet, going through the whole thing) 2009-05-08 09:19:48 +00:00
Pierre Alliez c26e8531e1 AABB tree: intersections now return CGAL::Objects. 2009-05-07 21:03:21 +00:00
Camille Wormser bf4043be63 replaced Point_and_primitive by Point_and_primitive_id and Object_and_primitive_id 2009-05-07 13:18:02 +00:00
Camille Wormser 6316ee39fe I revert the change, because this is, in my view, really important for having a sound design. 
Otherwise, what do you do if the sphere has no intersection with the data?
 2009-05-07 11:51:00 +00:00
Pierre Alliez 8e754e6e7c AABB tree: (ref manual): all hints back to point types in distance queries - I believe that's little relevant to ask a primitive as hint. 2009-05-07 11:33:26 +00:00
Camille Wormser 4b720e0c06 documentation compilation issues 2009-05-07 11:30:29 +00:00
Pierre Alliez db287f0e56 AABB tree: more on internal KD-tree used to accelerate the distance queries. 2009-05-07 10:51:01 +00:00
Pierre Alliez fd017c5595 AABB tree: first version of boost::optional for any* 
obscure compilation issue for now.
more on doc too
 2009-05-07 06:44:59 +00:00
Camille Wormser fe06803b35 I think that it is useful to mention that the KD-tree method allows 
not to have all the primitives sampled: otherwise, the user may have 
the feeling that at least one sample per primitive is a requirement.

Imagine a scene with many small objects. It makes perfect sense to 
sample each of these objects with just one point.

Camille Wormser f87800c489 removed all references to "projection", except in the very first paragraph of the intro, where it fits well. 
(see Laurent's remark)

Camille Wormser 6f050ab6ca tentative API for dealing correctly with the degenerate cases: 
it changes NOTHING to the existing code, except that
